Could rancher be private harbor proxy

hi all, I am new to use rancher to manage my kubernetes cluster. I met a problem below

i have 2 cluster(named cluster1/cluster2) deployed on 2 vlan, they cant access each other but can access rancher server.
cluster1 have a private harbor
cluster2 have nothing

i want to add a deployment in cluster2, but the images is in cluster1’s harbor
i want to know whether the rancher can be a proxy for cluster1’s harbor
or i will move the harbor from cluster1 to rancher node.
